Easy. Everything goes inside the venv. Activate your venv (likely 'source /home/pi/weewx-venv/bin/activate') then install and configure the MQTTSubscribe extension and also install its prerequisite module paho-mqtt with pip just like you did for v4. Other than the one added step to activate the venv the other real difference in v5 is that it is now "weectl extension install" not the old wee_extension command to install any skins or extensions via the extension installer.
https://weewx.com/docs/5.0/upgrade/#upgrading-to-v50 has the changes worth noting.
